Provides simple and efficient backflow prevention.
This check valve has no movable parts and consists only of two
components.
Animated
Characteristics of the check valve for the backflow prevention of liquid
and gaseous media:
- tight shut off under minimum back pressure
- shuts securely even in conditions of low impurification (sand)
- almost noiseless and gentle shutting (quiet, no hammering)
- low cracking pressure
- no movable, prone to wear parts (low in maintenance, long-lasting)
- shuts in media, in which mechanical valves stick (glucose, chocolate)
- good chemical resistance, corrosion-resistant
- easy and reasonable installation, even later (between flanges)
- functions simultaneously as a filter (protects pumps and
installations)
- secures the flow measuring (measuring error impossible because of
recoil)
- it operates in any direction
